BACKGROUND OF THE INVENTION

A number of sports games are conducted on a playing surface and involve a player striking a game object away from an opponent in order to be successful. Such sports games can include ice hockey, soccer, tennis and volleyball. Training methods for such sports can include a machine for projecting game objects to the side of the playing surface occupied by a player being trained so that the player being trained can practice and improve his/her skills by striking the game object. For example, tennis players often train by returning balls projected by a ball machine or hit by a trainer to their side of a tennis court to develop their ball return skills. Similarly, ice hockey, soccer and volleyball players practice by striking hockey pucks, soccer balls or volleyballs projected to their side of the game surface by a trainer or a machine. Targets and free kick walls are used in training ice hockey and soccer skills.

DESCRIPTION OF THE INVENTION

According to the invention, a method and apparatus for training sports skills for a game conducted on a playing surface that includes striking a game object away from an opponent can include projecting a plurality of game objects toward one portion of the playing surface, and selectively having one or more opponents appear at one or more locations on the playing surface in order to train the player to strike the game object away from an opponent. The addition of one or more opponents teaches the player being trained to strike the game object away from an opponent in addition to practicing striking the game object. In the case of games involving hitting or kicking a game object into a goal, one or more opponents can be arranged to appear at multiple locations in or in front of the goal to simulate a goalie to teach a player how to strike a game object past a goalie into the goal. The method and apparatus according to the invention can include, but need not include, projecting a plurality of game objects to the side of court occupied by the player being trained for training players to score in games involving striking or kicking a game object into a goal. For example, when method and apparatus according to the invention is applied to the game of tennis, the player being trained can be taught to play the court by training reaction time and placement memory in the brain of the player in addition to training muscle memory in returning the tennis ball. When a trainer is used to hit tennis balls to the side of the tennis court occupied by the player being trained there can be a tendency for the player being trained to hit the ball back to the trainer so that a volley can be sustained. However, training the placement memory of the player being trained to hit the tennis ball back to the trainer can be counter productive when it comes time to play a game of tennis when the object is to hit the tennis ball within the court where the opponent(s) can not return the ball. When the method and apparatus according to the invention is applied to the game of ice hockey or soccer, a simulated opponent can be arranged to act as a goalie movably mounted on, or in front of a goal to train placement memory by focusing the player being trained on striking the game object away from the goalie in addition to training muscle memory in making shots on goal.

Turning to FIG. 1 through FIG. 7, the method and apparatus for training sports skills applied to the game of tennis can be seen. Tennis court 5 can have a net 6, base lines 7, service lines 8 and side lines 9 as are well known. A player 10 being trained can be positioned on one side of tennis court 5. Referring to FIG. 3, a player 10 being trained can be positioned on one side of tennis court 5 and a trainer 11 can be positioned at the back line 7 on the opposite side of the tennis court 5. As will be described below, a ball machine can be used to project tennis balls to the side of the tennis court occupied by player 10 instead of a trainer 11. One or more opponents 12 can be positioned on the opposite side of tennis court 5 from the player being trained. Opponents 12 can be persons or can be simulated opponents that operate mechanically as described in greater detail below. Use of one or two opponents 12 can depend on whether the player is being trained in singles or doubles and can depend on whether the opponent is a person or is a simulated opponent the operates mechanically. In the embodiment of the invention as shown in FIG. 3, trainer 11 can sequentially hit a plurality of tennis balls to the side of the tennis court occupied by player 10, and can direct one or more opponents 12 to occupy selected locations on the opposite side of the tennis court so that player 10 can be trained to return the tennis balls away from the opponent(s) 12, thereby teaching tennis player 10 to play the tennis court and training placement memory in the brain of player 10 in addition to training muscle memory of player 10. Use of opponent(s) 12 arranged to occupy selected locations on the opposite side of the tennis court can also improve the reaction time of player 10 by requiring player 10 to observe to position of opponent(s) 12 and decide where to return the tennis ball. Thus, player 10 can be trained to develop muscle memory for skills of returning tennis balls to the opposite court, and can also improve reaction time and develop placement memory in the brain, namely, observe the location of the opponent(s) and return the ball away from the opponent(s). Opponent(s) 12 can be positioned on the opposite side of tennis court 5 to simulate where a player of a selected skill level would likely be positioned in relation to the tennis ball hit by trainer 11 to the side of the tennis court occupied by the player 10 being trained. For example, if trainer 11 hit a lob shot, opponent(s) 12 can be directed to the location(s) that an opponent of a selected skill level would take after hitting a lob shot. Player 10 will face a realistic situation of returning a lob shot to the opposite side of the tennis court occupied by an opponent or opponents, thus providing the opportunity to train the brain of player 10 to not only return the tennis ball hit by the trainer, but to decide in real time where to return the tennis ball, namely away from the opponents positioned on the opposite side of the tennis court 5.

Turning to FIG. 1 and FIG. 2, another embodiment of the invention, again applied to the game of tennis, can be seen. A player 10 being trained can be positioned on one side of tennis court 5. A plurality of simulated opponents 22 can be provided on the opposite side of tennis court 5. One or more ball machines 21 can be provided on the opposite side of tennis court 5. Simulated opponents 22 can be arranged to appear at selected locations on the opposite side of tennis court 5 under control of an opponent control 23. Simulated opponents 22 can be connected to opponent control 23 by control lines 24. Opponent control 23 and/or simulated opponents 22 can be provided with a suitable power source as described below. Those skilled in the art will understand that control lines 24 shown schematically in FIG. 1 and FIG. 2 can be mechanical lines to move simulated opponents 22 or can be electrical lines to operate selected ones of simulated opponents 22 to appear as will be described below. Those skilled in the art will also understand that control lines 24 can be wireless electromagnetic connections to the simulated opponents 22. While two simulated opponents 22 are shown in FIG. 1 and four simulated opponents 22 are shown in FIG. 2, the apparatus according to the invention contemplates using one or more simulated opponents 22 on the opposite side of the tennis court to simulate the play of one or two opponents in a game of tennis. The number of simulated opponents used can depend on the nature of the simulated opponent and can depend on the level of skill being trained.

One or more ball machines 21 can be provided behind base line 7 to project the plurality of tennis balls to the side of the tennis court occupied by player 10. Tennis ball machines are well known in the art and can be arranged to project tennis balls at a variety of speeds, directions, elevations and spins to simulate the play of opponents and different tennis shots. Ball machines 21 can be stationary or can be movable side to side in operation to simulate an opponent hitting tennis balls from multiple locations. In addition, a single tennis ball machine having multiple outlets can be used to simulate an opponent hitting tennis balls to the side of the tennis court occupied by player 10 from multiple locations. A game object or ball machine control 25 can be provided to control operation of ball machines 21. While one ball machine 21 is shown in FIG. 1 and two ball machines 21 are shown in FIG. 2, the method and apparatus according to the invention contemplates use of one or more than two ball machines or ball machines having multiple outlets to project tennis balls to the side of the tennis court occupied by player 10 depending on the capability of the ball machines to project tennis balls in various directions, whether movable ball machines 21 are used and the skill level be taught. Ball machines 21 can be connected to ball machine control 25 by control lines 26. Control lines 26 can be electrical lines or can be wireless electromagnetic connections as will be understood by those skilled in the art. As in the case of simulated opponents 22 and opponent control 23, ball machine(s) 21 and ball machine control 25 can be provided with a suitable power source that can include a battery, solar cell, connection to an electrical receptacle or portable generator as is well known in the art.

Opponent control 23 and game object or ball machine control 25 can be combined in a controller 28. Controller 28 can be programmed to operate ball machines 21 to sequentially project a plurality of tennis balls in selected combinations of direction, speed, elevation and spin, and to operate simulated opponents 22 to appear at selected locations on the opposite side of tennis court 5 to simulate the play of one or more tennis players having a selected skill level. Controller 28 can include a plurality of preprogrammed programs to simulate a plurality of skill levels. For example, controller 28 can be preprogrammed to simulate skills that can include grade school, high school, college, beginner, intermediate, advanced, professional, recreational, singles and doubles. Controller 28 can have a selector or selectors to set the game, i.e. singles or doubles, and the skill level. Controller 28 can also be provided with a timer to operate for a predetermined time, for example 30 minutes and can have a mechanism for processing payment by coin, currency or card. Controller 28 can be provided with a so-called smart card reader that can read the skill level programmed into the card and deduct payment from the card. A video recorder 29, see FIG. 2, can be provided to document the performance of the player 10 being trained to show the player how the player is striking the tennis ball, or to document improvement over time as is well known in the art. Video recorder 29 can be connected to controller 28 to control operation of the video recorder as is well known in the art. Controller 28 and video recorder 29 can be provided with a suitable power source that can include a battery, a solar cell, connection to an electrical receptacle or a portable generator, or other known power sources. A video recorder can be provided for any of the embodiments described in this application.

The embodiments of FIG. 1 and FIG. 2 can operate the method for training tennis skills as described above in connection with FIG. 3. Controller 28 can be arranged to simulate a selected skill level as described above. For each tennis ball projected by the ball machine(s) under control of ball machine control 25, opponent control 23 can cause one or more of the simulated opponents 22 to appear at one or more selected locations on the opposite side of tennis court 5. As in the embodiment of FIG. 3, the location or locations at which a simulated opponent or opponents 22 appear can depend on kind of shot the ball machine 21 is simulating (i.e. a serve, a lob shot, a cross court shot, etc.) and the selected skill level of the simulated opponent(s) 22. As in the case of the embodiment shown in FIG. 3, player 10 will face a realistic situation of returning a shot to the opposite side of the tennis court occupied by an opponent or opponents. Thus, the sports skills training method and apparatus of FIG. 1 and FIG. 2 provides mental exercise and the opportunity to train the brain of player 10 to not only return the tennis ball hit by the ball machine (muscle memory), but to decide in real time (reaction time) where to return the tennis ball, namely away from the opponents positioned on the opposite side of the tennis court 5 (placement memory).

Turning to FIG. 3A, another embodiment of the sports skills training method and apparatus for training tennis skills can be seen. In the embodiment of FIG. 3A a plurality of ball machines 21 can be provided along base line 7 of the opposite side of tennis court 5 from player 10 being trained. While two ball machines are shown in FIG. 3A, one or more ball machines can be used as discussed above depending on the capabilities of the ball machines and the skill level to be simulated. A plurality of stationary simulated opponents 30 can be provided on the opposite side of tennis court 5. In the embodiment of FIG. 3A three simulated opponents 30 are positioned along service line 8 and three simulated opponents 30 are positioned along base line 7. While six simulated stationary opponents 30 are shown in FIG. 3A, it is to be understood that any number of stationary simulated opponents can be used in the practice of the method and apparatus for training sports skills according to the invention. One or more simulated opponents, including more than six simulated opponents can be used depending on the nature of the simulated opponents and the skill level to be simulated. Stationary simulated opponents 30 can be positioned on court 5 to simulate typical locations occupied by a tennis player having a selected skill level. The stationary simulated opponents 30 can be arranged to appear at the location in which they are respectively positioned when respective ones of the stationary simulated opponents are activated by a simulated opponent control, not shown, as described above in connection with the embodiments shown in FIG. 1 and FIG. 2. Stationary simulated opponents 30 can take a number of forms and can be provided with a suitable power source, examples of which are described below. In operation the embodiment of FIG. 3A can be like the embodiments of FIG. 1 and FIG. 2. One or more of stationary simulated opponents 30 can be activated by an opponent control, not shown, to appear at a selected location in response to one of ball machines 21 projecting a tennis ball toward player 10 being trained. As described above, player 10 will face a realistic situation of returning a shot to the opposite side of the tennis court occupied by an opponent or opponents. Thus the sports skills training method and apparatus of FIG. 3A provides the opportunity to train the brain of player 10 to not only return the tennis ball hit by the ball machine (muscle memory), but to decide in real time (reaction time) where to return the tennis ball, namely away from the opponents positioned on the opposite side of the tennis court 5 (placement memory).

Turning to FIG. 4, another embodiment of the sports skills training method and apparatus for training tennis skills can be seen. In the embodiment of FIG. 4 a ball machine 21 can be provided along base line 7 of the opposite side of tennis court 5 from player 10 being trained. Ball machine 21 can be stationary or can be mounted on wheels or a track to be movable side to side in operation along base line 7 depending on the capability of the ball machine used to project tennis balls in a variety of directions and the skill level to be simulated. Ball machines movable side to side in operation can be used in other embodiments as will be readily understood by those skilled in the art. Ball machine 21 can be provided with more than one outlet to project tennis balls from more than one location to simulate an opponent hitting tennis balls from multiple locations or to simulate two opponents. While a single ball machine is shown in this embodiment, those skilled in the art will appreciate that two or more ball machines can be provided depending on the capability of the ball machine and the level of skill to be simulated. Two movable simulated opponents 32 can be provided on the opposite side of tennis court 5. In the embodiment of FIG. 4, movable simulated opponents 32 can be arranged to move side to side on tennis court 5, one simulated opponent 32 along service line 8 and the other simulated opponent 32 along base line 7. While the simulated opponents are shown movably positioned along the service line 8 and base line 7, the method and apparatus for training sports skills contemplates movably locating the simulated opponents at any position on tennis court 5 to simulate the play of a selected skill level as described above. Movable simulated opponents 32 can include a simulated tennis player mounted on a base that is movable side to side on tennis court 5. FIG. 11 discloses an example of a movable simulated opponent 32 that can include a simulated tennis player 33 mounted on a base 34. Base 34 can be mounted on wheels, not shown, to allow base 34 to move side to side on tennis court 5. Base 34 can be propelled by a motor driven wheel or can be moved back and forth across tennis court 5 by a cable. Simulated opponent 32 can be arranged to be movable in other ways in addition to the examples mentioned in the previous sentence as will be readily understood by those skilled in the art. Movable simulated opponents 32 can be controlled by an opponent control, not shown, to move to selected locations side to side on tennis court 5 in connection with projection of a tennis ball by ball machine 21 to simulate the position a tennis player or players would assume in response to the ball projected by the ball machine as in the case of the embodiments of FIG. 1 and FIG. 2 described above. Simulated opponents 32 can have a suitable power source as described below. A control for ball machine 21, not shown, and an opponent control, not shown, can be incorporated in a controller, not shown, all as described above.

Turning to FIG. 5, another embodiment of the sports skills training method and apparatus for training tennis skills can be seen. In the embodiment of FIG. 5 a ball machine 21 can be provided along base line 7 of the opposite side of tennis court 5 from player 10 being trained. Ball machine 21 can be stationary or can be mounted on wheels or a track to be movable side to side in operation along base line 7 depending on the capability of the ball machine used to project tennis balls in a variety of directions and the skill level to be simulated. While a single ball machine is shown in this embodiment, those skilled in the art will appreciate that two or more ball machines, or a ball machine with multiple outlets can be provided depending on the capability of the ball machine and the level of skill to be simulated. Two movable simulated opponents 32 can be provided on the opposite side of tennis court 5. In the embodiment of FIG. 5, movable simulated opponents 32 can be arranged to move front to back on tennis court 5, one simulated opponent 32 moving on one side of tennis court 5 and the other simulated opponent moving on the other side of tennis court 5. Simulated opponents 32 can be arranged to move from a position between service line 8 and net 6 to a position outside base line 7. It should be understood that the range of movement of simulated opponents 32 can be controlled by an opponent control, not shown, and can be selected to simulate the range of a player of a selected skill level. As in the embodiment of FIG. 4, simulated opponent 32 can be a simulated opponent as disclosed in FIG. 11 and can be mounted on a base 34 that is movable and can be provided with a power source as described below.

Turning to FIG. 6, another embodiment of the sports skills training method and apparatus for training tennis skills can be seen. In the embodiment of FIG. 6 a ball machine 21 can be provided along base line 7 of the opposite side of tennis court 5 from player 10 being trained. Ball machine 21 can be stationary or can be mounted on wheels or a track to be movable side to side in operation along base line 7 depending on the capability of the ball machine used to project tennis balls in a variety of directions and the skill level to be simulated. While a single ball machine is shown in this embodiment, those skilled in the art will appreciate that two or more ball machines, or a ball machine with multiple outlets can be provided depending on the capability of the ball machine and the level of skill to be simulated. Two movable simulated opponents 32 can be provided on the opposite side of tennis court 5. In the embodiment of FIG. 6, movable simulated opponents 32 can be arranged to move in any direction on tennis court 5. Movable simulated opponents 32 can be arranged to move front to back and side to side as illustrated by direction arrows 35, or simulated opponents can be arranged to be freely movable in any direction on tennis court 5. Simulated opponents 32 can be a simulated opponent as disclosed in FIG. 11 and operate as described above in connection with FIG. 4 and FIG. 5. Simulated opponents 32 that can move freely in any direction on tennis court 5 can include a base 34 comprising a robot movable in any direction under direction of an opponent control, not shown, incorporated in a controller, not shown. As in the case of the embodiments shown in FIG. 4 and FIG. 5, the movable simulated opponents 32 in FIG. 6 can be controlled by an opponent control, not shown, to move to selected locations on tennis court 5 in connection with projection of a tennis ball by ball machine 21 to simulate the position a tennis player or players would assume in response to the ball projected by the ball machine as in the case of the embodiments of FIG. 1 and FIG. 2 described above. As in the embodiments of FIG. 4 and FIG. 5, simulated opponents 32 can be provided with a power source as described below.

Turning to FIG. 7, another embodiment of the sports skills training method and apparatus for training tennis skills can be seen. In the embodiment of FIG. 7 a ball machine 21 can be provided along base line 7 of the opposite side of tennis court 5 from player 10 being trained. Ball machine 21 can be stationary or can be mounted on wheels or a track to be movable side to side in operation along base line 7 depending on the capability of the ball machine used to project tennis balls in a variety of directions and the skill level to be simulated. While a single ball machine is shown in this embodiment, those skilled in the art will appreciate that two or more ball machines, or a ball machine with multiple outlets can be provided depending on the capability of the ball machine and the level of skill to be simulated. A movable simulated opponent 32 can be provided on the opposite side of tennis court 5 from the player 10 being trained. Simulated opponent 32 can be arranged to travel on, or follow track 35 provide on the opposite side of tennis court 5. Track 35 can be a mechanical track or guide for simulated opponent 32 to follow as is well known in the art. Alternately, track 35 can be a wire or tape for simulated opponent 32 to follow using optical or electromagnetic sensors for following track 35, again as well known in the art. Simulated opponent 32 can be controlled by an opponent control to move to selected locations along track 35 on tennis court 5 in connection with projection of a tennis ball by ball machine 21 to simulate the position a tennis player or players would assume in response to the ball projected by the ball machine as in the case of the embodiments of FIG. 1 and FIG. 2 described above. Simulated opponents 32 can be provided with a suitable power source as described below. A control for ball machine 21, not shown, and an opponent control, not shown, can be incorporated in a controller, not shown, all as described above. While track 35 is shown in FIG. 7 as a generally rectangular track, those skilled in the art will recognize that track 35 can assume any desired shape in order to facilitate location of simulated opponent 32 is desired locations on tennis court 5 in order to simulate a player of selected skill level(s). Likewise, track 35 need not be confined to the bounds of tennis court 5 defined by side lines 9 and base line 7 as often tennis players move outside the lines of a tennis court in returning a tennis ball.

A number of simulated opponent embodiments can be seen in FIG. 8 through FIG. 15. While the simulated opponents are shown in FIG. 8 through FIG. 15 in a shape simulating a tennis player holding a racket, it should be understood that the simulated players could be formed to simulate an opponent for the sports game to be simulated. Turning to FIG. 8 and FIG. 9, a folding simulated opponent 36 can be seen. Simulated opponent 36 can have a wire form frame 37 representing the upper body of a tennis player. Wire form frame 37 can include the outline of a head and two arms; one raised and arranged to hold a tennis racket shaped form 38. Wire form frame 37 can be pivotally mounted to a base unit schematically represented as a cart 39 having a mounting surface 40. Wire form 37 can be pivotally mounted to mounting surface 40 by clips 41 engaging wire form 37 and fastened to mounting surface 40 by fasteners, not shown. Wire form frame 37 can be held in a vertical position by a spring 42 and cable 43. Cable 43 can be operated by control 44 that can include a crank 45 arranged to pull cable 43 through an opening 45 in mounting surface 40. With crank 45 in the position shown in FIG. 8 and FIG. 9, wire form frame 37 can be in the vertical position. When control 44 is activated, crank 45 can rotate pulling on cable 43 and thereby pivoting wire form frame 37 to a substantially horizontal position. When control 44 is deactivated, spring 42 can rotate wire form frame 37 back to the vertical position, thus causing the simulated opponent to appear. Control 44, and any mechanism to move cart 39, can be powered by a battery, solar cell or by connection to a power source that could be an electrical receptacle or a portable generator as will by understood by those skilled in the art.

Wire form frame 37 can have a suitable cover decorated to simulate a tennis player's face and body. Likewise, tennis racket portion 38 can be covered to simulate a tennis racket. Cart 39 can have resilient feet on the ends of the legs contacting tennis court 5, or can be provided with wheels, rollers or casters to facilitate movement of cart 39 to selected positions on a tennis court. While cart 39 is shown in FIG. 8 as a manually movable cart, it should be understood that cart 39 can be provided with a mechanism to move cart to selected positions on a tennis court as discussed in connection with FIG. 1 through FIG. 7 above. While a spring and cable mechanism is shown in FIG. 8 and FIG. 9 to operate simulated opponent 36, it should be understood that any suitable mechanism can be used to rotate wire form frame 37 between a vertical position in which the simulated opponent appears and a substantially horizontal position where the simulated opponent is “not present”. For example opposed springs or opposed cables and suitable operators could be used. Similarly, electromagnetic, pneumatic or hydraulic operators could be used to activate and deactivate the simulated opponent 36. The simulated opponent 36 can be made of material other than a wire form 37. The simulated opponent could be a foam board or other light weight, perforate or imperforate strong sheet material cut out in the form of a tennis player holding a tennis racket suitably hinged to mounting surface 40. Instead of being hinged to rotate front to back, wire form frame 37 can be hinged to tip to the side when “not present” and tip back to the upright position to appear. When wire form frame 37 is hinged to tip to the side, the operating arrangement can be adjusted accordingly as will be readily understood by those skilled in the art. Simulated opponent 36 can also be a full height figure rather than a half body figure as shown in FIG. 8, or the figure can be hinged in the middle allowing the top portion to fold to a substantially horizontal position while allowing the bottom portion to remain vertical. In the case of a full height figure, the mounting surface can be lower to the tennis court than shown in FIG. 8. An advantage of a half body form as in FIG. 8 is that the height of the simulated opponent from the pivot point is less than for a full figure thereby reducing the force and time need to move the simulated figure to a vertical position and back to a folded or substantially horizontal position. It should be understood that the sports training method and apparatus according to the invention includes a full or partial form simulating an opponent.

Turning to FIG. 10, another embodiment of a simulated opponent can be seen. In the embodiment of FIG. 10, pivoting simulated opponent 46 can include a wire form frame 37 pivotally mounted to a base unit schematically illustrated as a cart 39 like the cart in FIG. 8. Cart 39 can include a mounting surface 40 that can have a shaft 48 projecting through the mounting surface for rotatably carrying wire form frame 37. Shaft 48 can extend to operator 47 that can be arranged to rotate shaft 48, as shown by rotation arrow 49, between a position with wire form frame 37 facing the player 10 being trained on court 5, not shown in this figure, and a position facing the side lines 9 of tennis court 5, not shown in this figure. Operator 47, and any mechanism to move cart 39, can be powered by a battery, solar cell or connection to a power source as described above in the embodiment of FIG. 8. When wire form frame 37 is positioned facing player 10, the simulated opponent appears as an opponent for player 10 to avoid in returning the tennis ball projected to the side of the tennis court occupied by player 10 as described above. When wire form frame 37 is rotated facing the side lines 9, the simulated opponent is “not present”. For example, the mechanism to operate shaft 48 can be a well known target positioning apparatus as used in rifle ranges. Simulated opponent 46 can be used in the embodiments of FIG. 1 through FIG. 7 as discussed above. Like the embodiment of FIG. 8, cart 39 can be stationary or movable. Cart 39 can be manually movable or can be movable under control of a control or controller to simulated movement of a tennis player having a selected skill level. The simulated opponent can be a foam board or other light weight, strong perforate or imperforate sheet material cut out in the form of a tennis player holding a tennis racket suitably attached to shaft 48. Likewise, as in the case of the embodiment shown in FIG. 8, the simulated opponent can simulate a full body as opposed to the half body form shown in FIG. 10.

Turning to FIG. 11, another embodiment of a simulated opponent can be seen. In the embodiment of FIG. 11, a simulated opponent 32 can include a wire form frame 33′ mounted to a base unit 34.
